Be it known-that I, HERVE)! R. KUMLER, a citizen of the United States, residing" at Etiwanda, in the count of San Bernardino andvState of California, ave inventeda new and useful Shock-Absorbing Vehicle-Wheel, of which the following is a specification.

This invention relates to spring wheels, and the main objects ofthe invention are to provide a shock absorbing vehicle wheel the spokes of which may be-construct'edof wood and to provide a substantial and practical end of the barrel and means for securing the spokes to the hub.

Further objects are to provide a wheel .of the character described which is simple in construction, effective in operation and dura ble in use.

The accompanying drawings illustrate the invention, and referring thereto:Figure 1 is a side elevation of the wheel. Fig. 2 is a sectional view on line to -a Fig. '1.

.The hub of the wheel comprises a barrel 1- having a flange 2 with a conical recess 3 at the junction of the flange with the barrel. A sleeve 4,- the inner end of which is provided with a flange 2 similar to the flange on barrel 1, is slip ed on the barrel 1. In order to hold the s eeve 4 in position on the end of the barrel 1, a sleeve 4 is screwed on to the barrel; and a dust-cap '5 is screwed onto the rotects the nut 6 on the end of axle 6. he sleeve 4' firmly holds the sleeve 4 in place, and enables the dust cap 5 to be removed when desired to give access to the interior of-the barrel wit-h.

out disturbing-or loosening any of the parts which hold the spokes in place. i

A large number of spokes 7 are employed, each spoke being constructed referably of wood, and being curved as s own. ,Eachspoke is tapered on each of its sides nearly to its inner end from whence two ofthe sldes are parallel for a short distance for the engagement therewith of the flat portions of the flanges2 and the butt of each spoke is provided with a pair of lateral wed e shaped wings 8, which fit under the conical portions 3 of the flanges 2. The butt of each spoke is also formed wedge shaped, as shown m Fig. 1, so that when the s .okes' are assembled in position the dividing inesor joints between the butts of the respective spokes are radial to the axis of the barrel '1.' The spokes. are held in position by means of the, wings 8 which project under thesloping portions 3 of the flanges 2, and also by means of a series of Specification of Letters Patent.

. bolts or rivets 9, which pass through .the.

flanges 2 and between the spokes, each spoke having on each side of its inner end between the'wmgs 8 and the ta ering outer portion a half-rounded recess w ich receives its portion of the rivet 9, thus the spokes are absolutely locked in position on the hub. By loeating the recesses at this point, or within the length of the spoke having the parallel sides, the bolts 9 can pass through the fiat portions of the flanges 2 and draw them rigidly against the straight parallel sides of the spokes with a strain which is at right anglesto said 'sur faces, thereby securing I much more durable fastening than would be the case. with the strain a plied on inclined surfaces.

felly -10 by means of screw bolts 11, the fell being provided with sunken recesses, eac

forming a shoulder 12, and the recesses receive the respective ends of the spokes, the

end of each spoke abutting against the adj acent shoulder 12. the folly 10. It will be seen that on account of the ,curvaturelof the spokes the hub of the wheel is not rigid with respect to the rim of the Theouter en s of the spokes are fastened to the A tire 13 is mounted on wheel, but that in operation any jolts which are sustained by the rim will result in springing the spokes of the wheel without imparting any sudden jars to the hub. The braced construction of the spokes, and their secure attachment to the hub, prevents any dishing of the wheel.

What I claim is In a wheel, a hub having a flange at its inner end and a longitudinal bore at its outer end, the flange being conically recessed at its base and flat and perforated in its outer portion and the recessed end of the hub being on the outer end of the hub-1n engagement 'with said nut, a.felly provided with shoul-.

dered recesses upon its inner surface, a series of curved-spokes, the outer portion of each of which 'is tapered and fits in .one of said recesses, the inner end of each spoke being pros v'idedwitha pair of lateral, wedge shaped spoke and the felly.

In testimony whereof, I have hereunio set my hand at Etiwanda, ()aliii, this 23d day of Jai'iumry, 1907.
